Making the Right Choices for SOAP Scalability
This is an excerpt from the book Java Testing and Design: From Unit Testing To Automated Web Tests by Frank Cohen (Prentice Hall Publishing, Spring 2003, ISBN 0131421891). May. 19, 2004

Understanding SOAP Encoding Impact on Web Service Performance in WebLogic Workshop
WebLogic Workshop presents a compelling set of visual tools to enhance developer productivity to turn out SOAP-based Web services quickly. Workshop's designers have figured out a clean way to present the myriad of options found in the SOAP and WSDL specifications. Each option you choose impacts the scalability and reliability of your finished application. For example, a recent study of SOAP encoding styles showed a 30-fold performance improvement by choosing one SOAP encoding-style over the others. This article presents a way to understand the performance impact of SOAP encoding styles and shows how to build and test a Web service in Workshop for scalability and performance. Mar. 26, 2003
